SPECIFICATION forming part of Letters Patent No. 448,068, dated` March 10, 1891. Application tiled December 13, i890. Serial No. 374,560.. (No model.)

To a/ZZ whom t may concern:

Beit known that we, GEORGE C. PARMETER and ALEXANDER G. C. STnTsoN, both citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Carpet-Fasteners, of which the following is a specification.

The object of our invention is to provide a carpet-fastener which will permit of the expeditious laying or taking up of the carpet, and which is especially applicable to rooms orapartm ents having floors of asphalt or hard wood into which the ordinary carpet-tacks cannot be readily driven. This object we attain in the manner hereinafter set forth, referen'ce being had to the accompanying drawings, in which- Figure l is a perspective view illustrating our improved carpet-fastener and the mode of using the same. Figs. 2 and 3 are enlarged sectional views of the fastener, showing the same, respectively, open and closed and Figs. 4t and 5 are views illustrating modiiications of the invention.

In Fig. l, A represents part of the floor of the room or apartment, B part of one of the walls of the same, and D part of a piece of carpet or other covering to be secured to said floor.

IVhere rooms have iioors of asphalt or hard wood, the securing of the carpet to the oor by means ofordinary carpet-tacks is impracticable, and expensive fastening devices have been proposed for use in such cases. Our invention, however, comprises a cheap and simple device for the purpose, this device consisting in the preferred form of a plate F, to which is pivoted so as to be free to swing an arm G, said arm having at its lower end a portion a bent at right angles and confined by a raised or offset portion b of the plate, the outer end of said portion c, being bent upward, as at d, into a recessed portion f of the plate, so that when the latter is applied to the tloor around a chimney-hearth or away from the wall the arm cannot be detached, although it is free to swing to the desired extent. The upper or outer end of the arm G has a linger gbent outward at a right angle and terminating in atongue h,bent at a right angle to the iinger g-that is to say, at an angle of about ninety degreesin respect to the arm G, tlie latter swinging in a plane parallel with the edge ot' the carpet, so that when the edge of the carpet is applied tothe retainer, as shown in Fig. l, the finger g will project out over the carpet, and on depressing` the arm the tongue h will penetrate the carpet some distance from the edge of the same.

The plate F is secured to the iioor by suit- 6o able pins t', and in said plate is an opening m, which is located above a recess n in the fioor, and occupies such relation to the pivot portion b of the plate that when the arm G is turned downward the tongue h will pass through said opening m and enter the recess n.

In securing the carpet, therefore, all tliat is necessary is to bring the edge of the same close to the arm G and then swing said arm downward, so as to cause the tongue 71, to 7o penetrate the carpet and enter the recess n in the floor, as shown in Fig. 3, and in removing the carpet it is simply necessary to raise the edge of the same, so as to pull the tongue out of the recess and thus permit the release of the carpet from said tongue. In order to prevent the accidental release of the retainer, however, the end of the tongue is curved, first forward and then rearward, as shown in Figs. 2 and 3, so that as the arm G is de- 8o pressed, a beveled or inclined portion of the tongue 71. will come in contact with the edge of the opening m in the plate F, and said tongue will be caused to spring inward to a slight extent, so as to permit the curved por- 8 5 tion of the same to pass through the opening, the tongue springing forward again as soon as this curved portion has passed through the opening, as shown in Fig. 3, so that said curved portion of the tongue will engage with the 9o plate and prevent the raising of the arm G, unless soine little force is exerted to so raise it.

The use of the plate with the opening m is not absolutely essential to the proper carrying out of our invention, as the inger may, if

desired, simply project downward into the recess in the iioor, or it may be retained by frictional contact with one of the walls of this recess, which may have a lining-thimble p, as

shown, for instance, in Fig. 5, one side of this roo thimble being preferably roughened, so as to retain the tongue 7L, which bears upon said roughened side. Other means than the plate F may also be used as a means for securing the retainer to the floor. For instance, in Fig. 4 we have shown a couple of staples F as the securing means for the retainer, the plate being preferred in all cases, however, as it renders unnecessary any fitting or adjust- 1n entof the arm G in respect to the opening nl'. Having thus described our invention, we claim and desire to secure by Letters Patentl. The Within-described carpet-retainer, consisting of an arm pivoted to the floor, so as to swing in a plane parallel with the edge of the carpet, and having at its free end a lateral projecting nger 'for overlapping the edge of the carpet, said projecting finger having a forwardly-extending tongue for penetrating the carpet, substantially as specified.

2. The combination of the arm pivoted to the floor, so as to swing in a plane parallel with the edge of the carpet, and having a latemily-projecting finger with tongue for penetrating the carpet, with a plate confining said arm to the floor and having an opening for the passage of said tongue, substantially as specified.

3. The combination of the recessed floor or floor-plate with the arm pivoted to the floor, so as to swing in a plane parallel with the edge of the carpet, and having a laterallyprojecting finger with elastic penetrating tongue, and means for pivoting said arm to the floor, substantially as specified.

In testimony whereof we have signed our naines to this specification in the presence ot two subscribing Witnesses.
